Description Jonathan Holloway 2013-08-30 02:04:13 UTC

Description of problem:
Running posix_compliance causes smbd to crash during ELOOP tests when DIST_REPLICATE volume is mounted on RHEL5.9 via cifs.

Version-Release number of selected component (if applicable):
RHS 2.1 (glusterfs 3.4.0.24rhs-1)

How reproducible:
Every time

Steps to Reproduce:
1. Create a 6x2 DIST-REP volume
2. Mount volume on client via CIFS
3. Run posix_compliance test

Actual results:
smbd crashes and posix_compliance test hangs

Expected results:
Expect smbd to not crash and posix_compliance test to complete

Additional info:
If the specific test processes are killed, posix_compliance moves on until it reaches the next ELOOP test and crash/hang repeats.

The tests hanging are:
chmod/06.t
chown/06.t
link/08.t
mkdir/08.t
mkfifo/07.t
open/12.t
rename/11.t
rmdir/05.t
symlink/07.t
truncate/07.t
unlink/07.t

We have some fixes going in the latest build which fix some crashes, can we test with latest build? glusterfs-3.4.0.29rhs or later

Comment 4 Jonathan Holloway 2013-08-30 18:19:56 UTC

I am also able to reproduce the problem on glusterfs-3.4.0.30rhs-2

I am not seeing the problem on glusterfs-3.4.0.20rhs-2

Comment 5 Vivek Agarwal 2013-09-05 16:53:47 UTC

We tried running this on glusterfs-3.4.0.31rhs and it passed.

Comment 6 Jonathan Holloway 2013-09-06 00:51:21 UTC

Thanks Vivek.

I ran the posix_compliance job against glusterfs-3.4.0.31rhs setup as described above and it did not hang for me either.

Changing to verified.
